Please follow this guide and post the requested diagnostics, thanks!

Definitely a bug here, I can reproduce it easily:

$ brew rm darkice celt
Uninstalling /usr/local/Cellar/darkice/1.2...
Uninstalling /usr/local/Cellar/celt/0.11.1...
$ brew install darkice --cc=llvm-gcc
==> Installing darkice dependency: celt
Error: comparison of Fixnum with nil failed

Note this is on 10.9 where there is no true llvm-gcc.

[jacknagel]

For completeness: there doesn't seem to be a need to use llvm, it compiles fine with clang.

[jacknagel]

This is this bug: #18781

I'm going to add a nil check to Formula#fails_with? in the interim.

[jacknagel]

Hmm, after adding the nil check, there is yet another bug: https://gist.github.com/jacknagel/8919488

==> make install
Making install in src
llvm-g++ -DHAVE_CONFIG_H -I. -I/usr/local/include -I/usr/local/include  -I/usr/local/include  -I/usr/local/include -I/usr/local/include    -O2 -pedantic -Wall    -c -o AudioSource.o AudioSource.cpp
Your Xcode and or CLT are mis-configured. Try some or all of the following:
    xcodebuild -license
    sudo xcode-select -switch /path/to/Xcode.app
make[1]: *** [AudioSource.o] Error 1
make: *** [install-recursive] Error 1

My expectation is that it wouldn't attempt to use llvm-gcc (since it is just a symlink to clang).

[wbill]

Ok, you said use clang, I'm new to clang any idea how I should proceed? Thanks for the help!!!

[jacknagel]

Basically don't use --use-llvm. Any advice that says to do this is outdated, and most recent systems don't have llvm-gcc anymore anyway. Clang is the default these days.
